9 Claims.

This invention relates to attachments for use in connection with typewriters, and has for its object to provide an attachment that will serve to guide a plurality of superimposed strips of paper, with means thereon for supporting carbon sheets interleaved between the strips of paper.

It is particularly the object to provide an attachment in the nature of a frame, which has means for engaging a typewriter at one end, guide means at its other end with intermediate means for temporarily supporting one or more sheets of carbon paper, and so supporting the sheets of carbon paper that they may be easily removed therefrom for use in connection with strips of paper for writing purposes.

This invention also relates to a method of feeding sheets of carbon paper, interleaved between strips of paper, and supporting the sheets of carbon. paper so that the strips of paper may be fed independently thereof.

These and other advantages will appear from the following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a side elevation of the attachment attached to a part of the typewriter, with the strips of paper and interleaved carbon sheets thereon, with the carbon sheets supported so that the strips of paper will travel independently of the carbon sheets.

Figure 2 is a view similar to Figure l but with the upper part of the frame of the attachment broken away to show a connecting rod and the guides for the strips of paper, and showing also the carbon sheets unsupported and moving with the strips of paper.

Figure 3 is a front elevation.

Figure 4 is a section through the interleaved strips of paper, carbon sheets and the pasteboard strips for supporting the carbon sheets.

This attachment consists essentially of a frame composed of two side members I, connected at their lower ends by a lower cross member 2, and adjacent their upper ends by an upper cross member 3 (Figure 3). The ends of the lower cross member extend laterally from the frame to provide extensions 4, which have extending downwardly therefrom legs 5. Each leg has on its lower end a hook 6 to engage a rod 1 of the typewriter 8. This typewriter has the usual platen 9.

The central parts of the cross-members 2 and 3 are connected by means of a central bar I 0. Each side member adjacent the upper cross member is bent to form a shoulder or ledge II, as clearly shown in Figures 1 and 2. These shoulders serve to support the carbon sheets when it is desired to advance the stripsof paper independently of the carbon sheets. The upper end of each side member, beyond the upper cross member, is bent to form an arch or arcuate mem- .ber 12. These arcuate parts of the side members re connected by means of a rod l2a-, which not ly serves to connect the upper ends of the side members but acts as a support for the strips of paper passing over them and between two guide l3, located on the ends of the rod.

The superimposed strips of paper l4 have cross perforations H, by which the strips are marked off into sheets of paper (Figure 3). These sheets of paper overlie or are superimposed'one upon the other. vided, adjacent one end, with holes I6 for any suitable purpose. The sheets of carbon paper, interleaved and suspended between the strips of paper, are indicated by the numeral l'l. Each sheet has on its upper end a narrow, thin pasteboard strip l8 (Figure 4) which extends laterally from each side of the carbon sheet for support- These sheets of paper are also proing the carbon sheet, when desired, on the shoulder ll.

When a group of carbon sheets is used for the purpose of interleaving them between a plurality of strips of paper, the ends of the pasteboard strips are held together by means of a,cap or wrapper I 9; By means of these caps or wrappers the pasteboard strips are held in proper relation to one another. V described as made of pasteboard and pasteboard makes very serviceable strips, other materials may be used for this purpose.

In Figure .2 the typewriter is in operation and the superimposed strips and interleaved carbon sheets are being advanced together. The carbon sheets do not extend to the end of the assembly of strips so there is apart of the end of the assembly of strips that may be engaged by the typewriter for feeding without feeding the carbon sheets.

After the writing has been finished the platen is caused to rotate so that the strips of paper and sheets of carbon move backwardly. After these have been moved back sufficiently so that the strips l8 may be positioned on the shoulder While,these strips are I I, the paper strips are advanced sufliciently that they may be advanced with the advancement of the strips of paper. The writing action is again repeated with an additional section. of paper sheets in use, the paper sheets formerly written upon having been torn oil.

I desire to comprehend withinv my invention such modifications .as may be embraced within my claims and the scope of my invention.

Havingthus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A typewriter attachment for supporting a sheet of carbon paper interleaved between strips of paper, said sheet of carbon paper having at one end lateral projections, said attachment consisting of a frame having side members bent ad-. jacent one end of the frame to form shoulders for receiving the projections.

2. In a typewriter attachment for supporting a sheet of carbon paper interleaved between strips of paper, said sheet of carbon paper having at one end lateral projections,"a frame having sidemembers bent adjacent one end of the frame to form shoulders to receive the projections, and legs on the other end of the frame to engage the typewriter.

' 3. In a typewriter attachment for supporting a sheet of carbon paper between strips of paper, said sheet of carbon paper having at one end lateral projections, a frame having side members bent adjacent one end of the frame to form shoulders to receive the projections, legs on the other end of the frame to engage the typewriter,

member adjacent the arcuate end, said shoulders being adapted to receive said projections for supporting the sheets of carbon paper, and means on the other ends of the sidemembers for attaching the frame to a typewriter.

5. In a typewriter attachment for guiding a plurality of superimposed strips of paper and supporting sheets of carbon paper interleaved between the strips of paper, each carbon sheet having at one end lateral projections, a frame having side members, one end of each side member being arcuate and connected to the other arcuate end by ,a rod, means on the rod for guiding the strips of paper, a shoulder on each side member adjacent the arcuate end, said shoulders being adapted to receive said projections for supp rting the sheets of carbon paper, and means on the other ends of the side members for attaching the frame to a typewriter.

6. In a typewriter attachment for guiding a plurality of superimposed strips of paper and supporting sheets of carbon paper interleaved between the strips of .paper, each carbon sheet having at one end lateral projections, a frame having side members, one end of each side memher being arcuate and connected to the other cuate end by a rod, guards projecting up from e rod to guide the strips of paper, a shoulder said cross member adjacent a leg and having its other end arcuate and bent adjacent the arcuate part to form a shoulder, a rod connecting the arcuate ends, and an upper cross member connecting the side members adjacent the shoulders.

8. A typewriter attachment for guiding a plurality of superimposed strips of paper and supporting sheets of carbon paper interleaved between the strips .of paper, said attachment comprising a frame consisting of a lower cross member having at each end a leg, side members, each side member being attached. at one end to said cross member adjacent a leg and having its other end arcuate and bent adjacent the arcuate part to form a shoulder, a rod connecting the arcuate ends, guides for the strips of paper on the rod, and an upper cross member connecting the side members adjacent the shoulders.

9..An. attachment. for a typewriter having a platen and pressure feed roll, comprising a frame disposed on the feeding side of the typewriter, spaced stationary projections fixed to the outer marginal portions of the frame outside the path of the work sheets and at a distance from the operative zone of the platen and pressure feed roll I at least equal to the length of a carbon sheet,

holder is held immovably, irrespective of the movement of the work sheets during a feeding operation with 'the carbon sheet entirely removed from the operative zone of the platen and pressure feed rolls of the machine.
